Definitions

• the present invention relates generally to tongue cleaners, i.e., articles which are used to scrape the upper surface of a person's tongue.
• tongue cleaners are found in U.S. patents D221,036 and D338,084, which issued to Dasan Potti, one of the applicants of the present application.
• a portion flares outwardly to support, at an end of the tongue cleaner, a tongue scraping edge. The edge is moved over the tongue's upper surface from rear to front perhaps 2 to 3 times firmly scraping the upper surface.
• Such a tongue cleaning exercise is performed, after brushing teeth, to cause the taste buds to "wake up" and halitosis to diminish.
• tongue cleaning by use of such a device may minimize tooth decay and gum disease (gingivitis) .
• a tongue cleaning device cleans the tongue gently and smoothly.
• the anterior portion of the tongue may be easily reached by the tongue cleaners in the above patents, the posterior part of the tongue extends or slopes downwardly so that it is not as easy for a tongue cleaner to reach this posterior portion. Thus, it may uncomfortably require the person to tilt the shank up to the roof of the mouth, which many persons may choose to ignore to do.
• a tongue cleaner portion which supports the edge portion for scraping the tongue is skewed relative to the shank to slope downwardly, following the downward slope of the posterior portion of the tongue, for effective engagement of the edge with the posterior portion of the tongue without the user having to uncomfortably tilt the shank toward the roof of the mouth.
• Fig. 1 is a top plan view of a tongue cleaner which embodies the present invention.
• Fig. 2 is a bottom view thereof.
• Fig. 3 is a side view thereof, illustrated scraping the posterior part of a person's tongue, the opposite side being identical thereto.
• Fig. 4 is an end view thereof.
• Fig. 5 is another end view thereof.
• Fig. 6 is a perspective view illustrating use thereof in cleaning the tongue.
• the tongue cleaner 10 includes an elongate shank portion 16 for holding in the user's hand 18 for tongue cleaning, as hereinafter discussed.
• a portion 20 extends from one end of shank 16 and flares outwardly therefrom to support at an end of the tongue cleaner an edge portion 22.
• the sides of the support portion 20 extend outwardly from the sides of the shank so that the width, illustrated at 48, of the support portion 20 (for reaching of the tongue) is greater than the width of the shank (for easily holding in the hand 18) .
• the edge portion 22 which is shaped like a fender, is concave as viewed from the shank 16 and provides an arcuate edge 24 which contacts or engages the tongue 12 for scraping thereof, the edge being arcuate in order that the posterior portion of the tongue may be more easily reached without unnecessarily increasing the tongue cleaner width.
• a pair of oblong holes, illustrated at 26, are provided through the support portion 20 and extend parallel to the sides thereof respectively in order to provide increased flexibility.
• the posterior portion, illustrated at 28, of the tongue upper surface generally extends downwardly from the anterior portion thereof, as illustrated in Fig. 3, so that it is uncomfortable to reach with a straight tongue cleaner such as shown in the aforesaid patents.
• the support portion 20 is skewed relative to the shank portion 16 to slope downwardly for effecting engagement of the edge 24 with the posterior part 28 of the tongue upper surface.
• the support portion 20 lies in a plane, illustrated at 30, which forms an angle, illustrated at 34, with a plane, illustrated at 32, in which the shank portion 16 lies, and the edge 24 faces away from plane 32.
• support portion 20 extends at the angle 34 relative to the shank portion 16.
• the angle 34 is desirably selected so that the support portion 20 may follow the decline in the posterior part 28 of the upper tongue surface.
• this angle 34 is between about 20 and 40 degrees. More preferably, this angle 34 is about 27 degrees.
• the edge portion 22 is contoured over its length to have a relatively deep central portion, illustrated at 38.
• the central portion 38 has a depth, illustrated at 40, which is greater than depths, illustrated at 42, thereof toward the sides of the support portion 20.
• a suitable tongue cleaner 10 has a length, illustrated at 44, of perhaps about 5 inches so that the edge 24 reaches the posterior of the tongue, a shank portion length, illustrated at 46, of perhaps about 3 1/2 inches, and a thickness generally of perhaps about 1/16 inch.
• the edge portion 22 extends over a distance, illustrated at 48, cross-wise to the shank portion 16 of perhaps about 1 1/2 inches. Distances 40 and 42 are perhaps about 1/4 inch and 1/8 inch respectively. Angle 34 is perhaps about 27 degrees.
• the thickness of edge 24 may perhaps be about 1/64 inch.
• the width, illustrated at 50, of shank portion 16 may perhaps be about 3/8 inch.
• the distance, illustrated at 52 may perhaps be about 1/2 inch.
